  • Resistance of Plasmodium spp. to anti-malarial drugs is the primary obstacle in the fight against malaria, and molecular markers for the drug resistance have been applied as an adjunct in the surveillance of the resistance. In this study, we investigated the prevalence of mutations in pvmdr1, pvcrt-o, pvdhfr, and pvdhps genes in temperate-zone P. vivax parasites from central China. A total of 26 isolates were selected, including 8 which were previously shown to have a lower susceptibility to chloroquine in vitro. For pvmdr1, pvcrt-o, and pvdhps genes, no resistance-conferring mutations were discovered. However, a highly prevalent (69.2%), single-point mutation (S117N) was found in pvdhfr gene. In addition, tandem repeat polymorphisms existed in pvdhfr and pvdhps genes, which warranted further studies in relation to the parasite resistance to antifolate drugs. The study further suggests that P. vivax populations in central China may still be relatively susceptible to chloroquine and sulfadoxine-pyrimethamine.

  • The Oriental Medicine is described with so many terms of its own theory causing misunderstand of the concept which is expressed with same term used in modern medicine. Muscular system is also used in the both medicines, the Oriental Medicine and modern medicine. For the purpose of resolving the misunderstand of using the medical terms, we referred to a large number of literature for the muscular system in both medicine. Although there are few references concerning about systematic components in the Oriental Medicine, among the concepts of the Oriental Medicine, there are comparatively many approaches to the Meridian muscular system, a muscular system related with the Meridian, Therefore, there are many similarities and differences in the interrelation between the muscular system which was stated at the time of the concept of the Meridian system was developed and anatomical muscular system in the modern medicine. As a result of survey the references, we found out that anatomical muscular system is limited to visual compartments, whereas the Meridian muscular system is covering not only visual components but also the relation with internal organs. We conclude that there are conceptual differences in the kyung-keun system in the past and anatomical muscular system in the present.

  • Since the publication of the first bone scintiscans in 1962 three decades have elapsed. The bone scan has made great strides during this period, becoming one of the most commonly used nuclear imaging tests. In spite of the progress, however, the specificity of bone scan has remained relatively low. As the result it is a common practice to seek additional information from radiograph, CT scan and MR image, which is euphemistically termed as "image fusion or co-location." The basic reason is the inapplicability of the classical piecemeal analysis to interpreting planar and SPECT bone scans. Such analysis has its base on the observation of elemental features of morphology, which include the size, shape, contour, location, topography and internal architecture. The physiochemical profile may well also be included. Understandably, however, the miniatured images of the planar bone scan cannot provide these features in acceptable detail and the same holds true even with SPECT Images which are but sliced views of the reconstructed planar scans. Fortunately pinhole scanning has the capacity to portray both the morphological and chemical profiles of bone and joint diseases in greater detail through true magnification. The magnitude of pinhole scan resolution is practically comparable to that of radiography as far as gross anatomy is concerned. Thus, we feel strongly that pinhole scanning is a potential breakthrough of the long-lamented low specificity of bone scan. This presentation will discuss the fun-damentals, advantages and disadvantages and the most recent advances of pinhole scanning. It high-lights the actual clinical applications of pinhole scanning in relation to the diagnosis of infective and inflammatory diseases of bone and joint.

  • Light-emitting diodes (LEDs) based on III-nitrides compound semiconductors have achieved a high performance device available for display and illumination sector. However, the conventional c-plane oriented LED structures are still showing several problems given by the quantum confined Stark effect (QCSE) due to the effects of strong piezoelectric and spontaneous polarizations. The QCSE results in spatial separation of electron and hole wavefunctions in quantum wells, thereby decreasing the internal quantum efficiency and red-shifting the emission wavelength. Due to demands for improvement of device performance, nonpolar structure has been attracting attentions, since the quantum wells grown on nonpolar templates are free from the QCSE. However, current device performance for nonpolar LEDs is still lower than those for conventional LEDs. In this study, we discuss the potential possibilities of nonpolar LEDs for commercialization. In this study, we characterized current-light output power relation of the a-plane InGaN/GaN LEDs structures with the variation of quantum well structures. On-wafer electroluminescence measurements were performed with short pulse (10 us) and low duty factor (1 %) conditions applied for eliminating thermal effects. The well and barrier widths, and indium compositions in quantum well structures were changed to analyze the efficiency droop phenomenon.

  • This study is aimed at the application of the apparel size system to be applied for the Internet shopping mall in Korea. Especially this is focused on the presumption of the body measurement according to the age groups and the figure groups. In this regard, a sizing system is to be developed that could be used to approach consumers more easily and provide more fitness and accuracy in terms of size. The target study was on a group of women nineteen to forty-nine years of age. The 4th National Anthropometry Survey data were used in the examination. The results in the study are as follows ; (1) On the Internet apparel shopping malls in relation with this study, no matter what size in the ready-to-wear enterprises was selected by the consumers who once put their information in the member registration, the most appropriate sizes for them are automatically given and transferred to the order forms of chosen enterprises with aid of internal programs of the internet webpage. In addition, when consumers enter their body sizes in the units that are familiar to them, such as inches or centimeters, the units are automatically programed so that they can be converted for the sake of convenience. ; (2) To extract an estimation equation of body size through Multiple Regression Analysis, the circumferences of chest and hip could be presumed by stature, weight, and waist circumference of which most consumers were well aware. For more accurate regression equations, groupings were made in the three categories of age(19∼29/30∼39/40∼49) and in the three body types(Type N, A and H). Then, the regression equations were established for three sectors, $\circled1$ 'chest circumference not filled up', $\circled2$ 'hip circumference not filled up' and $\circled3$ 'neither filled up for chest nor for hip circumference'. The final results of regression were presented in

    • Objectives: Shape of face has relations with body shape and body weight in the Korean medicine. We investigated a correlation between a body mass index (BMI) and Dam-Bangkwang Body of Hyung-Sang medicine. Methods: The subjects were 244 adults aged from 45 to 64. A facial shape diagnostic equipment was used to classify Bangkwang Body or Dam Body. Statistical analyses were performed with the SPSS program to compare the correlation of BMI in each group. Results: We measured BMIs of the subjects who have Dam Body or Bangkwang Body which ranges were $22.53{\pm}2.83$ and $24.43{\pm}2.90$, respectively. The BMIs of Dam body subjects were significantly higher than those of Bangkwang Body subjects statistically (P<0.001). In order to verify our hypothesis, we also speculated BMIs of the obese with a BMI over 25. The BMIs of Bangkwang Body subjects were also higher than those of Dam Body subjects (P=0.001). With the width of the face of all subjects, we found that Bangkwang Body subjects whose the width of the face was relatively long had higher levels of BMI and obesity than Dam Body subjects whose height of the face was relatively long. Conclusions: The BMI of the Bangkwang Body is statistically higher than the Dam Body.

    • This study is conducted to understand the social value of Nakwon building, which has been instilled in the architecture of the building, through an analysis of formative elements unique to the center. The architectural characteristics of Nakwon building have been formed over a long period of time in relation with its surroundings and social change. Before looking into the formation of the center, this study investigates the street network planning of downtown. The street network was planned to expand in a north-south direction in order to accommodate a future increase of traffic volume as a result of industrialization and a population increase in downtown. This was manifested in expanding Samilro Street which passes through the lower part of Nakwon building, as well as in forming the architecture of the center. That is, the center has formed a symbiotic relationship with its surrounding areas, sharing space with them. The interior of the center seems to have an independent form while keeping a relationship with its external format, but it is seeking change internally in response to external change. Interior space has been departmentalized over time since its initial establishment, and the internal traffic has also been subdivided accordingly. This is attributable to the fact that social change in the neighboring areas affected the formation of Nakwon building, and that in turn contributed to forming the unique characteristics of the building. Nakwon building is one of the deteriorated buildings in downtown Seoul. However, it was built out of social need to share space within the city, and it has been changed according to social need for the 'distribution of space within the building.
